    Great Watch / Uncomfortable Strap

  • I received this watch as a replacement HR monitor. My previous Timex HR chest strap was rubber/silicone and very comfortable.

    This replacement elastic chest strap chafes my skin on runs more than 30 mins. I've adjusted the tension and it still rubs me raw and I have to wait for the sores to heal before wearing it again.

    Great watch, bad strap.
    Wear at your own risk.
